Checking for a Hardware Problem

If you suspect a hardware problem, use the Apple Hardware Test application to help
determine if there’s a problem with one of the Mac Pro components.

To use Apple Hardware Test:

1

Disconnect all external devices from your Mac Pro, except the display, keyboard
and mouse.
If you have an Ethernet cable connected, disconnect it.

2

Restart your Mac Pro while holding down the D key.

3

When the Apple Hardware Test chooser screen appears, select the language you
want to use.

4

Press the Return key or click the right arrow button.

5

When the Apple Hardware Test main screen appears (after about 45 seconds), follow
the onscreen instructions.

6

If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
error code before pursuing support options. If Apple Hardware Test doesn’t detect a
hardware failure, the problem may be software related.
